minor : fixes for ratoml module

This is a follow-up PR to rust-lang#17058.

- Parse errors are reflected as such by defining a new variant called `ConfigError::ParseError`
- New error collection has been added to store config level agnostic errors.

EDIT : Some things that this PR promised to solve are removed and will be addressed by other PRs
